SAP CRM - Prevent replication of Z-identification type to ECC

I've customized a new Identification Category & Type. While replication of my BP with the additional identification type, the corresponding BDOC shows the following error: "Identification Category &1 Does Not Exist" (R1/548).

This new type should be only available at CRM system. I don't want a replication to ECC system.

Is there any possibility maybe via customizing to avoid the replication of customer specific identification types?
